This species has been collected from leaf litter in rainforests from a restricted area of northern Queensland.
Identification
Shattuck (2009) - Carinae on pronotum and anterior mesonotum “V”-shaped; sides of head behind compound eyes smooth; antennal scapes with low longitudinal ridges; body smaller (HW < 0.70). This species can be separated from all other known Australian species by the combination of “V”-shaped sculpturing on the dorsum of the mesosoma and the small body size.

Description
Worker
Antennal scapes with low ridges. First segment of funiculus cone-shaped. Sides of head behind compound eyes smooth. Sculpturing on dorsal surface of mesosoma broadly “V”-shaped anteriorly, narrowly “V”-shaped medially and parallel posteriorly.
